All the info is in the subject. When I plug it in, the MBP screen flashes solid blue and then to regular mode. In the past it does this and then shows up on screen but it hasn't been doing that for the past week. I haven't swapped out my VGA or DVI to VGA cables. Any ideas from anyone with the same TV type and connections know how to fix this?

Make sure you plug the DVI-VGA adapter in while the VGA cable is connected to it. I've run into the same thing when connecting just the DVI adapter and then subsequently connecting the VGA cable to it.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

OK, sounds like you're using an RGB connector on your TV and not a VGA. I have no experience with doing this, so I can't accurately guide you here.

On my TV, there is a VGA connector. What I do is leave the VGA cable attached to the TV all the time. Then I connect the VGA to the VGA to DVI adapter, then plug the whole thing, already connected, into my MacBook Pro's DVI port. The MacBook pro discovers it automatically and outputs the display. I have had instances where it did not, for whatever reason, but I can usually force it through System Preferences => Displays.

The audio cable should not make a difference either way.

Maybe I am phrasing it wrong. It is RGB (a PC input). I have attached photos. This is how I have always connected it to my MBP. Also, I went to System Properties and it sees the TV as a second display but it won't send the signal. I have clicked on every setting and tab in there!!

Lucky for me, I found the same VGA to DVI adaptor at work in an empty conference room which is odd since its completely a PC environment. No guarantees that it works but I am going to bring it home and try it. I also have a new VGA cable to use as well.

For anyone that cares, I changed my VGA cable and that seemed to resolve this issue. Let's see if it happens again with a new cable. If it does it would probably mean that the TV or MBP are damaging these cables somehow.

I'm doing the same (DVI to VGA from macbook pro) and the TV monitor shows my background wallpaper but not anything else! So the computer output is getting through but not the right output. Any ideas? Is this a mac "user" issue?

I imagine that you have the displays set up to extend the desktop rather than "mirror." Check the mirror box in your display preferences.
